An exception thrown as a DataTruncation exception
(on writes) or reported as a
DataTruncation warning (on reads)
when a data values is unexpectedly truncated for reasons other than its having
execeeded MaxFieldSize.

Constructor Summary

Creates a DataTruncation object
with the SQLState initialized
to 01004 when read is set to true and 22001
when read is set to false,
the reason set to "Data truncation", the
vendor code set to 0, and
the other fields set to the given values.

Constructor Detail

DataTruncation

Creates a DataTruncation object
with the SQLState initialized
to 01004 when read is set to true and 22001
when read is set to false,
the reason set to "Data truncation", the
vendor code set to 0, and
the other fields set to the given values.
The cause is not initialized, and may subsequently be
initialized by a call to the
Throwable.initCause(java.lang.Throwable) method.

Parameters:

index - The index of the parameter or column value

parameter - true if a parameter value was truncated

read - true if a read was truncated

dataSize - the original size of the data

transferSize - the size after truncation

DataTruncation

Creates a DataTruncation object
with the SQLState initialized
to 01004 when read is set to true and 22001
when read is set to false,
the reason set to "Data truncation", the
vendor code set to 0, and
the other fields set to the given values.

Parameters:

index - The index of the parameter or column value

parameter - true if a parameter value was truncated

read - true if a read was truncated

dataSize - the original size of the data

transferSize - the size after truncation

cause - the underlying reason for this DataTruncation
(which is saved for later retrieval by the getCause() method);
may be null indicating the cause is non-existent or unknown.

Method Detail

getIndex

public int getIndex()

Retrieves the index of the column or parameter that was truncated.

This may be -1 if the column or parameter index is unknown, in
which case the parameter and read fields should be ignored.

Returns:

the index of the truncated paramter or column value

getParameter

public boolean getParameter()

Indicates whether the value truncated was a parameter value or
a column value.

Returns:

true if the value truncated was a parameter;
false if it was a column value

getRead

public boolean getRead()

Indicates whether or not the value was truncated on a read.

Returns:

true if the value was truncated when read from
the database; false if the data was truncated on a write

getDataSize

public int getDataSize()

Gets the number of bytes of data that should have been transferred.
This number may be approximate if data conversions were being
performed. The value may be -1 if the size is unknown.

Returns:

the number of bytes of data that should have been transferred

getTransferSize

public int getTransferSize()

Gets the number of bytes of data actually transferred.
The value may be -1 if the size is unknown.
